3.3-V, 1:1 (SPST), 4-channel FET bus switch

The SN74CBTLV3126 quadruple FET bus switch features independent line switches. Each switch is disabled when the associated output-enable (OE) input is low.

This device is fully specified for

partial-power-down applications using Ioff. The Ioff feature

verifies that damaging current does not backflow through the device when powered

down. The SN74CBTLV3126 device has isolation during power off.

To verify the high-impedance state during power up

or power down, tie OE to GND through a pull down resistor; the minimum value of the

resistor is determined by the current-sinking capability of the driver.
